The stator is a core component of the outboard's ignition charging system, generating the AC current that feeds the engine's ignition and charging circuits; a failed or weak stator can cause hard starting, intermittent misfires, loss of charging output, or a no-spark condition. This unit is built to a 40 amp output rating and is designed to replace the original stator on qualifying Mercury and Mariner 6-cylinder powerheads.\u003c\/p\u003e\u003cp\u003eSierra part number 18-99215 is compatible with 2000-2007 Mercury\/Mariner outboard engines rated 135, 140, 150, 175, 200, and 240 HP. It directly replaces OEM stators carrying the part numbers 398-858404A3, 398-858404A4, 398-858404T4, and 4398-858404T3, allowing it to be installed as a drop-in ignition system component without modification on the applicable engines. Always cross-check your outboard's existing stator part number before ordering to confirm an exact match for your specific engine.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-99215\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Mercury Outboard Ignition System\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 736983860170\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Engine Configuration:\u003c\/strong\u003e 6 Cylinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Rating:\u003c\/strong\u003e 40 Amp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Horsepower:\u003c\/strong\u003e 135, 140, 150, 175, 200, 240 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Years:\u003c\/strong\u003e 2000-2007\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Make:\u003c\/strong\u003e Mercury, Mariner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 398-858404A3, 398-858404A4, 398-858404T4, 4398-858404T3\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury\/Mariner 6-cylinder outboards, 2000-2007\u003c\/li\u003e\n\u003cli\u003e135 HP, 140 HP, 150 HP, 175 HP, 200 HP, 240 HP\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e398-858404A3\u003c\/li\u003e\n\u003cli\u003e398-858404A4\u003c\/li\u003e\n\u003cli\u003e398-858404T4\u003c\/li\u003e\n\u003cli\u003e4398-858404T3\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-99215 stator fit?\u003c\/strong\u003e The Sierra 18-99215 stator fits Mercury\/Mariner 6-cylinder outboard engines from 2000-2007 rated at 135, 140, 150, 175, 200, and 240 HP.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does 18-99215 replace?\u003c\/strong\u003e This stator replaces OEM Mercury\/Mariner part numbers 398-858404A3, 398-858404A4, 398-858404T4, and 4398-858404T3.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the amp output rating of this stator?\u003c\/strong\u003e Sierra 18-99215 is rated for 40 amp output, matching the charging requirement of the 2000-2007 Mercury\/Mariner 6-cylinder engines it fits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-99215 stator weigh?\u003c\/strong\u003e The stator weighs 2.5 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does a stator do on a Mercury outboard?\u003c\/strong\u003e A stator generates the AC current used by the outboard's ignition and charging system;
